Disable gdb's native language support, and name every leak at once

gdb was the one component still building with NLS, so on Intel macOS it
linked Homebrew's libintl -- a library no user's machine has, which is
why the dependency audit refused the SDK. Its siblings all disable it
already.

The audit now reports every unexpected dependency before failing rather
than the first: each one costs a full build to find, and a host that
drags in one library from the machine tends to drag in several.
